Super Mario Galaxy 2 Wiki Guide

Flip Swap Galaxy - Green Stars

As soon as you get to the electric fences, flip the panels so the red ones are in place. You should see a shadow under the Green Star which sparkles just above the camera's frame. To get to this one, you'll need to perform a triple jump. Move near the 1-Up Mushroom and perform three short jumps while running towards the Green Star. You'll see Mario perform a small jump, a higher jump and then a tall jump marked by a unique flip. Spin at the top of the jump to reach the distant Green Star.
